Hello,

I have to index around 300,000 documents on AWS EC2 instance.

Can anybody please suggest whether I should go for a single instance or consider multiple instances for indexing ?

Thanks & Regards,  
Siddharth.

Depends.  
But you should be able to do it on one machine.

@warkolm  
Thanks for the reply !  
Yes I am able to do on one. I am just worried about the efficiency. Will multiple small machines be better than a single large machine ?

Regards,  
Siddharth.

Again, it depends.

What sort of efficiency are you looking for exactly?
